Question

One label on a package of bolts says that each bolt has a diameter of 0.45 inch. To be in the package, the percent error of the diameter must be less than 4%. A test on the production line shows a bolt with a diameter of 0.43 inch. Should this bolt go into the package?​

Answer 1

Answer:

• No, should not

Step-by-step explanation:

The diameter is 0.45 in

The percent error is < 4%

The lower limit of allowance is:

• 0.45 - 4% =
• 0.45*(1 - 0.04) =
• 0.45*0.96 =
• 0.432

Less than 4% error means the diameter should be greater than 0.432 in.

The bolt with the diameter 0.43 in is outside of the allowance and should not go into the package
